Look down a short way in the column on the right side of your screen, until you find Tech Support & FAQ. Click there.
Slide down this page until you reach Ultimate Family Tree 2.8 Maintenance Release . . .Click there.
Download and install version 2.8. I think there are instructions for doing that.
After 2.8 has been installed on top of 2.0, you may want to download the onscreen manuals. I am not sure if you get to choose a manual for 2.8. 'Cause there are several changes in the program version 3.0 and if the manuals are 3.0 you get frustrated trying to do stuff that 2.8 won't do.
You should't need any patches for 2.8 but if you do, you know where to find them now.
Now, use the instructions for the browser setup. Those instructions do work on version 2.8.
Also, if you open UFTree and click "Help and About . . .", it will probably still say you are using 2.0.Do something, such as making a change, however minor, in a record. Save the change (F9). Go right back and change the item back to what it was before so you don't forget. Press F9 again. Now, the "Help, About . . ." will probably tell you it is version 2.8.
